People can be severely addicted to alcohol to the point of physical dependence.

"The mortality rate from severe alcohol withdrawal and delirium tremens (DT) historically has been as high as 20% if untreated. Early recognition and improved treatment has reduced the mortality rate from DT to approximately 1-5%"

So this means people either die or go to emergency care with severe symptoms that require hospitalization, which obviously is to be avoided at a time like this.

Alcohol withdrawal can be fatal in some cases. I have a childhood friend who had multiple seizures from alcohol withdrawal and is it in a semi vegetative state.

Withdrawal symptoms of alcohol addiction can be pretty severe.

Withdrawal symptoms (primarily seizures, I believe) can be lethal.

I think the OPs point would be it would lead to more aggression and that then would lead to the more deaths.

Now I don't know if that link exists and in fact I suspect it could be the opposite, as many people become more aggressive the more they drink.
